Feedback mechanisms make different contributions to warming, depending on the region of the world. The contributions of lapse-rate, snow/ice albedo, Planck, cloud, and water vapour feedbacks to warming for the Arctic and for the Tropics are shown for a modelled climate state in which carbon dioxide concentrations are quadrupled from their pre-industrial levels. Feedbacks in the red-shaded area of the figure contribute to enhanced warming in the Arctic relative to the Tropics, whereas feedbacks in the blue-shaded area contribute to enhance warming in the Tropics relative to the Arctic.
